"If a ship had 26 sheep and 10 goats onboard, how old is the ship's captain?"

How is the amount of cargo a ship contains supposed to help you figure out how old the captain is?

The internet had a lot to say about this seemingly impossible math question, which became a trending topic on Twitter.

One person did come up with a solution.

A commenter on Weibo, a popular microblogging site in China, thought of a way to determine the captain's age based on the ship's cargo.

"The total weight of 26 sheep and 10 goat is 7,700kg, based on the average weight of each animal," they wrote according to a BBC translation. "In China, if you're driving a ship that has more than 5,000kg of cargo you need to have possessed a boat license for five years. The minimum age for getting a boat's license is 23, so he's at least 28."

According to school officials, the goal is to promote critical thinking.

After the test question went viral, the Shunqing Education Department released a statement saying that the question was meant to "examine... critical awareness and an ability to think independently," according to a BBC translation. If so, whether or not the math problem is solvable isn't relevant. The point is to encourage students to think creatively about possible ways to figure it out and come up with their own answers.

It doesn't matter if you're a math expert or not. If the question got you thinking, then you're just as smart as these 5th graders.
